44 Notes on the Distribution of Insects^ Sfc. 



Dermestid^b, Pyrrhid^, and Histeridje are eaually represented 

 in the north. They are of the same habits, destroying furs and 

 other animal substances ; species of the three families are fre- 

 c[ueatly taken together. Importing furs, &c., from America to 

 Europe may have been a souice by which some of the American 

 forms effected so extensive a distribution. Of Histerid^, the 

 representatives of four English species are now known to occur in 

 North America. 



Lamellicornia — Thirty-seven species of the following genera 

 inhabiting the United States, have been taken in Canada : Can- 

 thon, 1 ; Copy-is, 2 ; Onthophagus, 2 ; Aphodius, 3 ; Trox, 3 ; Geo- 

 trupes, 2 ; ^' Bolbocerus, 1 ; Lucanus, 3 ; Dorcus, 1, probably 2 ; 

 f Platycerus, 2 ; Passalus, 1 ; Xyloryoetes, 1 ; Pelidnota, 1 ; 

 Areoda, 1 ; Phyllophaga, 2 ; Omaloplia, 1 ; Serica, 1 ; Diche- 

 lonycha, 1, probably 2 ; Macrodactylus, 1 ; ? Valgus, 1 ; Osmo- 

 derma, 2 ; Trichius, 2 ; Cetonia, 2. 



Oearmbycid^ — The number as yet found in the United States? 

 north of Mexico, is 2*70, while in France 180 has been found, and 

 in England 64. The six following species — Criocephalus rusticus, 

 Hylatrupes bajvlus, Phymatodes variabilis, Clytus Gazella, Cal- 

 lidium sanguineum ? Monohammus sutor {?) Pachyta sexmacii- 

 lata appear to be identical with European species. The North 

 American forms of Lonfficorns seem to have a nearer relation to 

 those of Europe than to those of South America ; the same genera 

 being mostly found in both regions, to which some of the 

 northern forms are almost entirely confined, as. Oberea, Rhagium, 

 Pachyta, Strangalia, and Leptura. The PiiiONioiE are almost 

 fully represented in the western hemisphere ; the genus Elaplii- 

 dion, JJesmocerus, Tiitraojyes, Dorcaschema, and others are strictly 



* I believe this is tlie only species of the genus taken in Canada : — 

 Color ferrugineous ; Clypeus margined, granulate, and rounded in front 

 ■with two minute tubercles between the eyes ; thorax margined, densely 

 and minutely punctured, transversly elevated in front, with a longitudi- 

 nal furrow in the disc, and lateral black spot ; scutellum bell-shaped, 

 smooth, and very distinct ; elytra densely punctured in rows, about 16 

 in each elytron ; body pilose ; tibise toothed. Length 5 lines. Not 

 determined. 



t Of this genus two North American species, are already known. Mr 

 Ibbetson, late Assistant. Commissary General of Montreal says — that a 

 third one has been taken by him in Canada which differs in size and color 

 from quercus or depressus^ and that probably it is new.
